Becky Gallantree and Hannah Starling scraped through to the semi-final of the women's three-metre springboard at the Aquatics Centre this afternoon.
Gallantree failed to get past the preliminary round in Beijing four years ago but a score of 299.25 was enough to see her finish 16th and just inside the 18-diver cut.
Starling was fractionally behind her fellow Briton with a total of 298.95 placing her 17th.
The 17-year-old, the youngest diver in the competition, had been 19th heading into her final dive but drew scores of seven for her forwards two-and-a-half somersault with one twist to nudge through.
The City of Leeds duo will, however, have to improve to reach the final with the top 12 set to go through from tomorrow's round.
World champion Wu Minxia qualified in top position with a score of 387.95 ahead of compatriot He Zi, who she won the springboard synchro alongside earlier this week, in second.
